What it is
A cosmetic ingredient derived from the leaf cells of the common lilac (Syringa vulgaris) using plant cell culture technology. This method allows for a pure, standardized extract without harvesting whole plants.
How it works
It provides antioxidant activity by neutralizing free radicals that can damage skin cells. It also has soothing properties that may help reduce redness and sensitivity when applied topically.
Pros
Gentle on skin
Low irritation risk makes it suitable for sensitive skin types, unlike some stronger antioxidants.
Sustainable sourcing
Produced via plant cell culture, which reduces environmental impact compared to wild harvesting.
Cons and cautions
Limited research
Most evidence comes from lab studies; human trials are scarce, so effectiveness is not fully proven.
Lower potency
May not provide as strong antioxidant protection as more established ingredients like vitamin C or ferulic acid.
Best for
- People looking for gentle antioxidant protection
- Those with sensitive or reactive skin
Use caution if
- Anyone allergic to lilac or related plants
- Those seeking proven, high-potency antioxidant results
